Is the LG 75NU860BYUA good for movies?

Yes. The 75-inch 4K panel and α7 AI Processor 4K Gen9 give a large, detailed picture for films and streaming. Add a soundbar, since the built-in 20 W audio is modest for a screen this size.

Does it need a soundbar?

It is worth considering. Audio output is rated at 20 W, which is low for a 75-inch TV, so dialogue and bass will be thin compared with a dedicated soundbar or speaker system.

How big is it and will it fit my wall?

It measures about 65.7 inches wide, 37.9 inches high and 2.8 inches deep, and weighs around 48.7 lb. Check your wall or stand width before buying, and use a mount rated for its weight.

What is the α7 AI Processor 4K Gen9?

It is LG's picture processor for this set. It handles upscaling of lower-resolution content and general picture processing, which matters most on a large 75-inch screen where flaws are easier to see.

What is the warranty?

Coverage is one year for parts and labor. Keep the receipt, since LG handles service directly under that warranty.

Is it a good fit for a bright room?

It is a standard LED-backlit 4K set without advanced local dimming, so very bright rooms can wash out dark scenes. It performs best in moderate or controlled lighting.
